Abstract

The second hyperpolarizability (��) of carbon disulfide (CS2) is measured by gas-phase electric-field-induced second-harmonic generation for laser wavelengths in the range 765–1064 nm. The observed hyperpolarizability is decomposed into electronic (����) and vibrational (����) contributions, and the dispersion curve for ���� is extrapolated to the static limit, with the result of ����0=12558±93 atomic units =7.83±0.06×10−61C4m4J−3=6.33±0.0×10−36 esu (Taylor series convention). The results of this experiment agree with other recent nonlinear optical measurements and theoretical calculations.
